Theres different classes of servers, the 4U ones are pretty much as powerful as it gets, many sockets (usually 4) and a huge fabric.

1Us are extremely commodity, basically as “low end” as it gets, so I like to use them as if they are a baseline.

A 1U that can take 1.5TiB of ram might be part of the same series of machines that might have a 4U machine that could do 10TiB. But those are hugely expensive. Both to buy and to run
